Sudden Fish death - sensitive to iodine?

[bingojimbo]

I have a 26 gallon planted tank. Two days ago I added 2 drops of Kent Iodine in the water thinking that it would benefit the shrimps that i have in there. This morning I noticed that one of my furcata rainbowfish and my Checkerboard cichlid are dead! I regularly do a 50% water change every week. The only thing different that I have done was add the Iodine. Could that be the cause of death?

I still have:
6 furcata rainbowfish
1 signifer rainbowfish
1 albino bristlenose
3 licorice gourami
6 otto
1 SAE
1 balloon molly
5 amano shrimps
1 Indian Pearl Shrimp

THanks in advance!

Don't know what to tell you, bingo. I add 1/2 tsp of kent iodine to my tank each month. I've haven't lost a fish since a started dosing a few months ago. I don't have any of the fish you mentioned that perished. But I do have cardinals, rams, and a discus. Not exactly the 'hardiest' of fishes.
